The correct option is: B. 25x+40=415
The explanation is shown below:
1. You have that:
- There is $4.15 in the jar.
-There are 4 dimes in the jar.
2. Therefore:
1 quarter=25 cents
4 dimes=40 cents
$4.15=415 cents
3. Then, you have that the equation you would use to solve the problem and to calculate how many quarters are in the jar, is:
25x+40=415
